Just picked up a mv962 for a backup amp and I'm wondering if I should be able to use channel B by itself as a mono output? When I tried I got some serious crackle and intermittent signal. Channel A sounds just fine by itself. Is it not designed to use channel B alone or do I have an issue?

I've had a 962 for only a couple of months,and like it very much. It came with what looks like the original owner's manual. The manual says "for mono use channel A and set channel B controls to "0". Another section says "Stereo opperation is automatic whenan additional input is plugged into channel B. Hope that helps.

Yeah, I read through the manual, but I'm not certain if that means it will only function properly as a mono amp using channel A.

I agree - avoid DeOxit. That red stuff.. It gums up and attracts dirt. It's very popular, but sucks after a couple of years. But the same company makes stuff for faders. It's much nicer stuff than the normal DeOxit, works great on pots and switches and jack contacts. You get more than a couple years out of that stuff.

Honestly, the best thing I've found over the years is pure isopropyl (anhydrous) to clean and remove oxide, and then use a VERY tiny amount of white turbine or sewing machine oil to lubricate.
